I am leery of IMPLIED in this case. Authoring software must decide whether to show an element as a possible root. If a document doesn't state its preference, the authoring software will make its own decision. Thus, two editors might behave differently when given the same XSchema -- something I don't like. I think that Simon's (Recommended | Possible | Forbidden) probably does the best job here. That is, there is no technical reason most elements can't be used as roots; it's just not always a particularly useful thing. -- Ron Bourret xml-dev: A list for W3C XML Developers.
